WHEEL` CLAMP.

Application led. May' 1B,

T all whom# may concern.'

Be it knownthat I, FRANK RYNDZQNAK, a

. citizen of the lUnited States,l residing at Glidden, in the county 0f Colorado and State of Texas, ful Improvements in lVheel Clamps, which the following is a specification.

This invention .relates to clamps for at-v taching a wheel of a railway car or thelike to Vthe rail supporting such wheel and is es# pecially adaptedfor use in holding the Wheel stationary on the rail when the journal box -is to be lifted for renewing brasses or for like operations. V

Objects of the invention are, the production of a device which ymay be readily and quickly attached to the rail and wheel; which is simple in. construction and operation and economical to manufacture; which` will notfinterferey with the jack used for raising the journal box, and which may be disassembled. for `storage when notin use. .A further object is .to produce a device of the character referredto'which is adaptable to. varying conditions.

In the drawing: Y Fig. 1 is a perspective `view showing the device inoperative relation to a railand i wheel;

Fig. 2 a side elevation of the same on a slightlylarger scale than Fig. 1; and

Fig. 3 is a section on line 3-.-3, Fig. 2, showing the relation of the parts.

Referring to the drawingsY in detail, 10 designates an ordinary track rail, 11 the wheel of a car or the like running on said rail, and 12 the rim of said wheel.

In jacking up the journal boxes of a car wheel for inserting brasses or for any other purpose the car wheel should be locked against movement on the rail. For this purpose I have provided the device forming the subject-matter of my invention, which comprises an arm 13 adapted to rest upon the head of a rail and to project laterally therefrom. This arm is preferably rectangular in cross-section and is provided at one end with a jaw 14 which extends at substantially right angles to the arm and is adapted to hang down over and grip one side ofthe head of the rail. A second jaw 16, which is adapted to grip the opposite side of the head of the rail, is carried by an eye which corresponds in shape to the cross-section of the arm 13. The arm 13 extends through said eye and the jaw 16 is thus slidably have invented new and. use.

mounted on the arm 13. .The jaws 1 4 16 are provided atftheinlv'er. ends with horizontally 'extendingfportions '15, "andV 17,` respectively, which.N are` Vadaptedf to under-sides of. theV head of vthe rail.y These grip the portions 15 and 17 Aare preferably provided. Y.

with roughened. orv toothed surfaces .18 and 19 to vadapt them tdbetter .gripthe l'surface with which theyv contact. Anyrelative angular rmovement -beween the aws 14` and 16. will causetheeyeof the jaw 16 to bind on the arm 13 and thus ysecure the jaw v16 againsty movement longitudinally of they arm 13. i l' i y Y Slidably mounted onthc arm 13 in amanner Vsimilar to jaw` 16 is a' bracket arm 2O which, when the device is attached to a rail, extends in parallelism with the rail, the sliding connection between the. arm`20` andthe arm"13 beingy preferably in thevform of an eye 21 at or adjacent to onevend of said bracket arm, `through which eye the `arm 13 is adapted tof slide. .Thearm 20 curves down-` wardly from the eye 20 ,and thenI extends substantially inV a horizontal, plane. This. construction of the lbracket armk gives it a certainresiliencyfor a purpose which will hereinafter appear., `The end -of the arml 2O opposite the eye 21 is bent vertically upward toform a stem 22, Aas shownin Figs. 1 2, and mounted on portion is a clamp member.` 23 which is vertically .adjustable on thevertical stem'. 22 and is lheld ,against .accidental slippingfthereon by` the rough'e'n'ed surfaces 24 Von opposite sides of said stem. The clamp 23 has a projecting nose 26 laterally from the member 22 and to grip the rim 12 of a wheel and hold it locked to the rail.

On the end of the arm 13 I provide a turnbutton 25, which when in certain positions, namely, vertical and horizontal, will prevent the eye 21 of the arm 20 from slipping o of the arm 13, and when in other positions at 45 to the horizontal, will permit the removal of the said arm 20. By this construction the device may be disassembled for storage, or the arm 2O may be reversed in its position on the arm 13 and caused to extend in the opposite direction from that shown in the drawing.

In applying the device to a rail and wheel, the jaw 14 is hooked over one side of the head of the rail with the hook portion 15 under said head of the rail and the jaw 16 is this upwardly .extending j brought to a position with the projection 17 extending under the head of the rail on the other side thereof. The arm 20 is then adjusted upon the arm 13 so as to properlyposition the clamp 23 relative to the Wheel to be locked. The clamp is then brought down into contact with the flange of the Wheel and a crow-bar may be slipped under the arm 2O and the arm raised slightly, thereby allowing the clamp 23 to slide further down on the member 22. lVlienthe crowbar is removed, the resiliency of the arm 20 will draw the clamp 23 firmly against the Wheel, preventing` its movement along the rail.

Any movement of the wheel 11 on the rail 10 will, through the engagement of the clamp 23 with the flange of said Wheel, tend to rock the arm 20 and with the latter rotate the arm 13 by reason of the engagement of the eye 21 of the arm 20 with the arm 13. But such rotation of the arm 13 will be resisted by the engagement of the jaws 14 and 16y with the head ofthe rail and the sli ht resulting relative angular movement etween the jaws 14 and 16 will cause the jaw 16 to bind on the arm 13, thus securing the jaw 16 against movement longitudinally of the arm 13. Y

vWhat is claimed as new is: j'

1. A device for clamping a car ywheel to a rail, comprising a pair of jaws' for attachlng the deviceto a rail, a resilientk bracket arm, anda vertically adjustable clamp on said bracket arm adaptedto be brought into position against the flange of the Wheel.v

. 2. A devicek of the character described, comprising anarm having a jaw attached to the end thereof, a jaw slidable on said'arm and secured by angular movement relatively to said first-named jaw against movement longitudinally of said arm, said second` named jaw cooperating with the first named jaw to clamp the device to; a rail, a bracket arm adjustable on said first named arm, and a vertically adjustable clamp on said bracket arm. i

n 3. In a device of the character described, an arm having a jaw on the end thereof and an adjustable cooperating therewith to secure the'arm to a rail, a resilient bracket arm extending from said first named arm and adapted to lie in parallelism with the rail, and a vertically adjustable clamp se,- cured to said bracket arm.

4. A device of the class described, comprising an arm adapted to be secured to a rail and to extend laterally therefrom when so secured, a bracket arm adjustable on said first named arm having a vertically extending portion, and a clamp adjustably secured to said vertical portion, as and for the purpose described. v.

5. A device for securing a car wheel to a rail, comprising an arm adapted to be secured to the rail, a bracket arm adjustable on said first named arm, a turn-button on the end of the first named arm which, when in one position, prevents removal ofL the bracket arm from the firstnamed arm and which may be .turned to a position to permit removal of said bracket arm, and a clamp on said bracket arm.

6. A device for securing a car Wheel to a rail, comprising an arm adapted to be secured to the rail, a bracket arm adjustable and reversible on said first named arm, and a clamp on said bracket arm.

- In testimony whereof I have hereunto set my hand in presence of two subscribingwitnesses.
